A study of the impact strength of steel fiber R.C. bridge column elements for precast segmental bridge construction in seismic regions

摘要

Steel fiber reinforced concrete (SFRC), which provides high impact strength and ductility, can beused in segmental bridge construction to delay the crack and crush of concrete and absorb more energy underan earthquake. In this paper, ACI drop weight impact tests and modified ACI drop weight impact tests areperformed on both normal concrete and SFRC. The impact strength of normal concrete and SFRC are comparedand analyzed.
